  • preview_product_quote

    Download a saved quote's exact artwork PDF. All small and double-sided postcards include the selected recipient's illustrative address side; postage placement may vary. Other products return stored print artwork. Review before send_product_quote; reading never changes the quote o

    List reusable workspace cover-sheet designs and versions, plus defaultDesign matching the website's Reset defaults button. To reset a local draft, replace its design with defaultDesign; this read never changes saved presets. Render to preview, then save_cover_sheet only if the us
